The film, for track Gave It All Away, sees the remaining quartet sitting in a room remembering their friend, affectionately known as Steo, who died suddenly in October while on holiday in Majorca.

The band's Ronan Keating said: "We wanted the footage to be as truthful and honest as possible based on how we were feeling and were reacting during the making of the video on that day - it really reflects the whole day as it was."

The single was premiered on Ronan's new radio show on London station Magic 105.4. It is due to be released on March 1.

"We found it really hard to make this video and the footage is incredibly raw and tough to watch at times," he said. "But we didn't want it being too mournful all the way through."

Bandmate Shane Lynch said: "As you will see from the video, it was a very hard shoot for us boys to do but also enjoyable in a way as we all felt Steo around us that day.

"For me the single feels like the end of an old chapter but also the beginning of a new one for us all and we all know we are continuing on for the right reason."

The track has been written by singer Mika and features on forthcoming album Brother, which is released on March 8.
